Fluid treatment device and treatment method

Abstract

A fluid treatment device for treating an object to be treated between treating surfaces (1, 2) which can be made close to and away from each other so as to rotate in a relative manner, introduces a first fluid between the treating surfaces (1, 2), introduces a second fluid between the treating surfaces (1, 2) from another flow path (d2) independent of the first fluid, and mixes and stirs the first and second fluids between the treating surfaces (1, 2) to undergo treatment. A treating section (20) of the device is composed by assembling a plurality of divided treating section component members (20a, 20b). An opening (d20) and a flow path (d2) are formed in the space between the plurality of treating section component members (20a, 20b). This eliminates the need to create all ring-shaped disks which are the treating section (20) as one block, and also eliminates the need to substantially process the flow path (d2) leading to the opening (d20), thereby making it possible to easily undergo decomposition and cleaning.

Description

technical field [0001] The present invention relates to a fluid treatment device for treating an object to be treated between treatment surfaces in a treatment unit that can approach and separate at least one of them and rotate relative to the other. Background technique [0002] Microreactors and micromixers are provided as fluid processing devices using microchannels and microreaction containers. The possibility that the minute reaction field provided in such an apparatus affects the chemical reaction itself that has hitherto been performed in a beaker or flask is unknown (refer to Non-Patent Document 1). [0003] However, in the generally provided microreactors, the solids and gaseous precipitates generated by the reaction are clogged in the flow path, and eventually the flow path is blocked. Due to the high pressure loss, a large pump is required, and it cannot be enlarged. device, many problems. [0004] As described in Patent Document 1 or Patent Document 2 provided ...

AI Technical Summary

Problems solved by technology

[0005] However, even in the fluid processing device described in Patent Document 1 or Patent Document 2, there is still a case where solids etc. are clogged in the flow path provided with the opening between the processing surfaces in the processing part. It is difficult to clean the bottom; the flow path with the opening is difficult to process, and the processing part becomes an expensive part

In addition, in the aspect of enlargement of the research device, it is necessary to make a large processing part. When the method represented by sintering by heat treatment at high temperature is used to make all the ring-shaped disks as the processing part into one piece, As the diameter of the disk increases, a large molding machine, firing machine, etc. are required, so the manufacturing cost tends to increase, and the processing part becomes an expensive part.

[0006] In addition, when it is intended to mix the first fluid and the second fluid at a ratio of 1:1 between the processing surfaces, etc., it is preferable to use a device that has an annular opening on the processing surface, but it will be used during the processing. It is difficult to process and manufacture a processing part with a ring-shaped opening on the surface
